Answer:
part A) rearrange the equations to form simultaneous equations:
y-7x=8
y-5x=-2
now eliminate the y values by minusing the two equations:
(y-7x=8)-(y-5x=-2)
to get:
-2x=-6
x=3
now substitute x into one of the equations to get y:
y=5x-2
y=15-2
y=13
[tex]x = 3 \\ y = 13[/tex]
part B) the lines will intercept at (3, 13)

Answer:
Number 1: 1 2/4 or 1 1/2
Number 2: 2 4/6
Number 3: 5/6
Step-by-step explanation:
For Numbers 1 and 2... You'd have to separate the whole number from the fraction and subtract accordingly.
Number 1: 2-1=1 and 3/4-1/4=2/4
So you would get 1 2/4.
Number 2: 3-1=2 and 5/6-1/6=4/6
You would get 2 4/6
For Number 3 you would have to find the LCD (Least common denominator) for 1/2 and 2/3.
The answer will then be 5/6.
(I couldn't solve number 4 because it wasn't visible.)

Can u help solve this step by step?
Answer:
[tex]\sqrt{28}[/tex]
Step-by-step explanation:
It is given that the triangle (QRS) is right, thus one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states,
[tex](a)^2+(b)^2=(c)^2[/tex]
Where (a) and (b) are the legs or the sides adjacent to the right angle and (c) is the hypotenuse or the side opposite the right angle. The unknown side in the triangle is a leg, thus, let (b) represent this value. Substitute in the given values and solve,
[tex](6)^2+(b)^2=(8)^2\\\\36+b^2=64\\\\b^2=28\\\\b=\sqrt{28}[/tex]

Answer:
x = 2.3
Step-by-step explanation:
Since we know all three sides, what we do here is multiply side a & b's lengths together and divide by the hypotenuse. (a + b)/c
(2.5 * 6)/6.5
Step 1: Multiply 2.5 by 6 to get 15.
15/6.5
Step 2: Convert 6.5 into a whole number by multiplying it by 10. Make sure to do that to the 15 as well.
150/65
Step 3: 150/65 simplifies to 30/13 (GCF: 5).
30/13
Step 4: 30/13 becomes 2 4/13.
2 4/13
Step 5: 2 4/13 rounds to 2.3
2.3 is the value of x.
300% of what number is 75?.
Answer:
25
Step-by-step explanation:
Find the number by dividing 75 by 3, since 75 is the number tripled.
75/3
= 25
So, 300% of 25 is 75.
Answer:
25
Step-by-step explanation:
300% * x = 75
300/100 * x = 75
x = 75 * 100/300
x = 25

What is the combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Eight students are competing for a blue, red, and yellow ribbon for their agriculture project.
Different ways are there to present those ribbons if the order matters.
By permutations, we have to calculate the number of different ways to arrange the ribbon is;
[tex]=3 \times 2\times 1\\\\=6[/tex]
Now, we have to calculate the different ways to choose 3 winners from 8 is;
[tex]=8\times 7\times 6\\\\=336[/tex]
Therefore, the correct option is (b), 336 ways are there to present those ribbons if the order matters.

hundredth.
חו
A=
in?
Answer:
94.985in^2
Step-by-step explanation:
Given data
Diameter= 11inches
Radius = 5.5 in i.e 11/2= 5.5inches
The Area of a circle is given as
Area= πr^2
Substitute
Area= 3.14*5.5^2
Area= 3.14*30.25
Area= 94.985 in^2
Hence the area is 94.985in^2
The answer is 94.985in^2

Answer:
k = [tex]5\frac{1}{3} ,7\frac{1}{3}[/tex]
Step-by-step explanation:
|19 - 3k| = 3
-3k = 3 - 19
-3k = -16
k = 16/3
k = 5 1/3
-19 + 3k = 3
3k = 3 + 19
3k = 22
k = 22/3
k = 7 1/3

The question says find the missing angles HELPP
Answer:
y: 71 degrees
z: 71 degrees
v: 71 degrees
x: 54.5 degrees
w: 54.5 degrees
Step-by-step explanation:
Ok, I might be wrong, please don't hate me!!!!
Since all triangles are 180 degrees, you can find all the measure while knowing only one angle measure.
To find y and z, you need to subtract 180 degrees by 38 degrees:
180 - 38 = 142
Since there are two angles, you need to divide the answer by 2.
142 / 2 = 71 degrees.
Since y and v are directly across from each other, they are the same measure (71 degrees).
With measures x and w, you do the same process of subtracting 180 by the value you know.
180 - 71 = 109
Then divide by 2.
109 / 2 = 54.5 degrees.

What are the coordinates of R'after a dilation by a scale factor of 3, centered
at the origin, followed by the translation (x, y) - (x + 4, y)?
A. (10,4)
B. (10, 12)
C. (10, 16)
D. (18,12)
Given:
The coordinate of point R in quadrilateral RUST are (2,4).
R is dilated by a scale factor of 3, centered at the origin, followed by the translation [tex](x, y)\to (x+4,y)[/tex].
To find:
The coordinates of R' after dilation and translation.
Solution:
If a figure is dilated by a scale factor of 3, centered at the origin, then
[tex](x,y)\to (3x,3y)[/tex]
We value R(2,4).
[tex]R(2,4)\to R_1(3(2),3(4))[/tex]
[tex]R(2,4)\to R_1(6,12)[/tex]
The rule of translation is:
[tex](x, y)\to (x+4,y)[/tex]
Using this rule, we get
[tex]R_1(6,12)\to R'(6+4,12)[/tex]
[tex]R_1(6,12)\to R'(10,12)[/tex]
Therefore, the coordinates of point R' are (10,12) and the correct option is B.
